However, no matter how many clever gifts and gadgets you've got in your arsenal, you're about to get one more - because we'd bet you very good money that you haven't tried THIS.
Sydney-based dad Nathan Dailo shared this video of his 3-month-old son Seth and the unusual trick he uses to get him to nod off - and when we saw how simple it was, we couldn't believe our eyes!
At the beginning of the video, Seth is wide awake...
...but with a few gentle brushes with an ordinary sheet of tissue paper...
...he drifts off to the land of Nod - in less than 40 seconds!
Since Nathan shared the clip, it's been viewed by more than 150,000 sleep-deprived parents around the world.
Commenters on the vid are equally astounded, but eternally grateful. One wrote: 'This worked for my baby 5 times already so thanks!'
Nathan explains, 'You can try just about anything - we have found running your fingers over their forehead or over the bridge of their nose lightly will give the same effect too. We just thought a tissue would have a funny side to it! It's worked with a few others! :)'
